Simulation of Rainfall-Runoff Process Using Green-Ampt Method and HEC-HMS Model (Case Study: Abnama Watershed, Iran)
Estimation of surface runoff in a watershed based on the rate of received precipitation and quantifying discharge at outlet is important in hydrologic studies. In this study, HEC-HMS hydrological model version 3.4 was used to simulate rainfall-runoff process in Abnama watershed located in south of Iran. To compute infiltration, rainfall excess conversion to runoff and flow routing, methods like...
متن کاملComparative Study of HEC-HMS Rainfall-Runoff Model with Different Experimental Methods of Flood Estimation
The most important problem in estimating floods is the lack of sufficient statistics and consequently the lack of evaluation of the appropriate amount of flow. One of the flood estimation methods in these basins is the use of hydrological modeling. In this study, Shahbahram river flood modeling was performed with Nazmkan hydrometric station located in Kohkiluyeh Boyer-Ahmad province with HEC-HM...
متن کاملImpact of Watershed Management activities on flood hydrograph Using HEC-HMS Model (Case Study: Ramyan Watershed)
Increasing the use of water and soil resources in watershed in recent years and unproductive and inappropriate use of land ecology has exacerbated the occurrence of floods. In this context, watershed management is one of the most effective ways to cope with this crisis. This research quantify the results of these activities by calculating the decreased volume and discharge due to biomechanical ...
متن کاملAutomatic Calibration of HEC-HMS Model Using Multi-Objective Fuzzy Optimal Models
Estimation of parameters of a hydrologic model is undertaken using a procedure called “calibration” in order to obtain predictions as close as possible to observed values. This study aimed to use the particle swarm optimization (PSO) algorithm for automatic calibration of the HEC-HMS hydrologic model, which includes a library of different event-based models for simulating the rainfall-runoff pr...
متن کاملApplication of the HEC-HMS model for runoff simulation in a tropical catchment
Hydrologic simulation employing computer models has advanced rapidly and computerized models have become essential tools for understanding human influences on river flows and designing ecologically sustainable water management approaches. The HEC-HMS is a reliable model developed by the US Army Corps of Engineers that could be used for many hydrological simulations. This model is not calibrated...
